We bought the house with a decorative gas fireplace in the living room, and I use it very rarely, for example when visitors are here. Last night we had company and was visiting in the basement while the fireplace was on upstairs for about 5 hours. I was surprised how hot the main floor got (we have a large house with very high ceilings). This has me thinking about using it more.

Do you use your decorative gas fireplaces to heat the house in the winter?
